KANSAS CITY, Mo. – Pro Bowl running back Jamaal Charles returned to Chiefs practice with no hesitation Sunday despite a lingering right foot strain that caused soreness to travel halfway up his leg.

Charles spoke to reporters before hitting the practice field for the first time since last Monday, when he stepped on a teammate during the workout. He missed last Friday night's preseason game against San Francisco and his status for next weekend's game at Pittsburgh is undecided.

Rookie running back Knile Davis worked out with the first team while Charles was out.

Charles said it was the first time he'd had this type of foot strain, calling the injury "weird" and that "it was definitely scary" because it affected the way he runs.

When asked whether there was any hesitation about practicing Sunday, Charles said, "Oh no." The Chiefs are not scheduled to practice Monday.
